SHADE FASTENING'.

Application filed November 13, 1920, Seriali No. 423,536. Renewed August28, 1924.k

To all 'whom t may concern Be itY known that I, STEWART HAn'rsHoigN, acitizen of the United States, and a resi- .:zdent of Short Hills, countyof Essex, and

State of New Jersey,r have inventeda certain new and useful ShadeFastening, of which the following is a specification.

The invention relates to window shade rollers, and more particularly todevices for or for securing other articles, rsuch as drapery, to polesor other supports.

The objects of the invention are to provide means for securing shades orthe like `to hollow members, such as tubular shade rollers withoutinterferencek with the contents ofthe roller; by means of which theshade ,may `he firmly securedr in place without` injury to the roller;by means kof which the shade may be secured to the roller continuouslyfor the entire length of the roller `whethery the latter be of Wood ormetal; to provide means for securing the shade in position on the rollerwithout the useof tools, and which will prevent puckering or wrinllingof the shade, and to providey means whereby properly alining` the shadeon the rollerjmay be facilitated. j

y.These and further objects will more fully appearwin thefollowingspecification and accompanying drawings considered together orseparately. j y

One embodiment of the invention is illustrated in the accompanyingdrawings in whichI like parts in all of the figures are Y z beingromitted.

The invention will lirstbe y,described in connection with a tubularsheetz metal roller such as is commonly known as a ftinv roller. In thedrawings l designates such a roller which is rolled to form andsoldered,as, is common. One end of the roller is provided with a rectangularyspear 2, and thev opposite end carries a cylindrical pin 8 by means ofwhich the roller withthe shade 4 attached 1s mounted in a window frame.

The roller is rprovided with a series of perforations 5 and an equalnui'nberk oflon-A gitudinal slots 6, as` shown, by means of which afasteningstrip 7' may be secured to the surface of the roller. M

.The strip is preferably curved laterally to conform to the surfaceofthe roller,` and is provided at one end with a spur 8 which projectslongitudinally ofthe stripbut on a slightly lower plane. At the oppositeend the strip is provided with triangular lip 9 which isl folded alongits `base and. under the strip and parallel thereto for a portion atleast of its length.y y,The extremity: of the lip may be bent`dovviiward eccentrically with relation to the strip as shown in FigsA 5and 6. i f l j f When it is desired to apply a shade to the roller, theend edge of the cloth is `laid longitudinally rof the roller vanduin,Such a position that the vperforations. 5 and slots 6 are covered. rlhecloth over the perforation is now pierced by the spur8 andthe latter,when the strip ismoved; toward the position parallel to the roller.isshoved forwardv into the bore yof the roller, the slight bend l0 in thespur will permit the fspur to lie parallel with, andagainst the wall ofthe roller when the body of the strip is in position resting on thecloth and'parallel with the outside of the roller.V

Before the strip assumes the last mentioned position the Vapex'of thelipv 9 is pushed through the cloth and through the slot 6 nearest theperforation 5, Thelipped end is then moved laterally with respect to theroller, forcing the lip into the same and into frictional engagementwith the wall of the bore thereof. The shade is then folded back overthe strip and aroundthe.

Cfr

are similarly disposed along the roller whereby the entire edge of thecloth, except the slight gaps between the strips and short spaces at theends of the roller, is securely attached to the roller while the clothis pei'- forated at relatively wide intervals only. The pull of theshade on being` unwound will tend to hold the lip 9 in the slot 6, andthe said slot may be of any length desired whereby strips of variouslengths may be used.

Instead of placing the spur at the extremity of the strip as shown inFigs. l, 2 and 3, the spur 22 may be cut out at some distance from theend of the strip 23 as shown in Fig. 7.

In Fig. 8 the lip 24, instead of being located at the end of the strip,as before, is positioned a short distance from the end. By the use ofthe construction illustrated in Figs. 7 and 8 the strips used at theends of the roller may extend over the ferrules, when used, and to theextremities of the roller, and the shade will be secured to the rollerfor the entire length thereof.

In accordance with the provisions of the patent statutesthe principle ofthe inven tion, together with what is now considered to be the bestembodiment thereof, have been described, but it is to be understood thatthe apparatus described is merely illustra tive, and that the inventionmay be carried out in other ways.

The invention having been described what is claimed and desired to besecured by Letters Patent, is

l. An article of the class described, comprising a roller, there being aperforation in the roller, a member adapted to extend longitudinally ofthe roller, means for engaging one end of the member within theperforation, there being a longitudinal slot in the roller, and meansextending transversely of the roller for engaging the slot and securingthe opposite end of the member to the roller.

2. A device of the character described, comprising a tubular sheet metalroller of uniform cross section, there being a perforation in thecylindrical surface of the roller, a member adapted to extendlongitudinally of the outer surface of the roller and in proximitythereto, a spur projecting from the member and adapted to engage theinterior wall of the roller, there being a longitudinal slot in thecylindrical surface of the roller and at a distance from. theperforation, and means carried by the member and extending through theslot for elastically engaging the interior wall of the roller forsecuring the member to the roller.

3. A device of the character described. comprising a tubular sheet metalroller of uniform cross section, there being a perforation in thecylindrical surface of the roller,
